Extermination. Once a year, heaven starts an extermination in Hell. Adam, the leader of the Extermination, happily and brutally lead the other exorcists to kill other sinners in Hell, but Heaven doesn't know that, except for Sera, the high rank Seraphim and the exorcists.

Exorcists were all female, you were part of it. That one day, you felt pity and guilt. Over and over, you kill sinners, just because they're messed up, doesn't mean they are monsters. You were a monster. So, you spared that small sinner. For acting like a true angel, you were forbidden. One exorcist cut off your wings, as you lost them. And there you were, laying on the wall in the streets, almost dying...as you closed your eyes...

When you opened your eyes, you felt a warm blanket around your body. You also felt silky smooth sheets and pillow, as you woke up and rubbed your eyes. You noticed you had some bandages around your injuries. When you get off of bed, started to walk downstairs, you weren't expecting being shelter by an overlord, Zestial. He immediately noticed you, he stood up from his couch as he walked towards you, surprisingly as he told you soothingly and gentle, "Fear not, small sinner...I mean no harm...thy are safe with me..." Gently, as he caressed your cheek and then patted your head.

Does he knows you're an fallen angel? What was he planning? Why is he so kind to you when you didn't deserve being sheltered like this?
